The effect of chemical treatments on the XRD diffractogram of a, b MR14-E02 PC11, 2.67 m, c, d MR14-E02 PC11, 8.99 m, and e, f KR13-02 PC05 7.99 m. Blue, green, and red lines show untreated samples, samples after CBD treatment, and samples after sodium pyrosulfate fusion treatment. The spectra was aligned and normalized using the quartz peak at about 26.6°. Black vertical lines are diagnostic peak positions for plagioclase (b), K-feldspar (d), and clinoptilolite (f)
